Chapter 7: Using the VCode’s bar code reader<br />
VCode <strong>User</strong> <strong>Guide</strong><br />
About the bar code reader<br />
Introduction<br />
This topic describes what the bar code reader is used for, discusses bar<br />
code reader formats, and explains how the bar code reader can be<br />
controlled.<br />
What it is used for<br />
The VCode’s optional bar code reader can read a bar code on any side<br />
of the plate. It can be used to:<br />
❑ Read a bar code on a side of the plate that is not accessible to other<br />
bar code readers in a lab automation system.<br />
For example, the bar code reader on the robot of the BioCel ® can<br />
only read north-side bar codes.<br />
❑ Verify the identities of all plates that are brought into a lab<br />
automation system.<br />
❑ Verify the bar codes printed on plates at the VCode ® .<br />
❑ Read a bar code on one side of a plate and print an identical label<br />
on another side, except with a different bar code symbology.<br />
Diagram<br />
A diagram of the bar code reader attached to a bracket that is mounted<br />
at the side of the printer, is shown below.<br />

Laser light<br />
The laser light is projected as a series of lines, similar to the laser light in<br />
a supermarket checkout (cash register) scanner. It is not projected as a<br />
single point beam.<br />
About supported bar<br />
code symbologies<br />
It is important to understand that the ability of the printer to encode<br />
human readable text into a bar code is independent of the ability of the<br />
bar code reader to decode a bar code into human readable text. Just<br />
because you can print a bar code in a particular bar code format it does<br />
not mean that you can also read that bar code. The bar code reader<br />
must be configured to be able to decode the bar code format that is<br />
used to print the label.<br />
The bar code reader was preconfigured at the factory to support the four<br />
bar code formats that you are most likely to use, according to<br />
discussions with someone in your organization. If you now want to use a<br />
different bar code format, you will have to change the formats that are<br />
stored in the bar code reader.
